Havent had any luck upgrading the firmware yet, but i will try using a newer version of the tool provided.
Maybe a newer version will have better compatibility with W10.
Heres a link i found with newer versions for download.

I was easily able to update mine using this version of the tool (1.01.02) instead:
I haven't had a lot of time to test it out, but the menu definitely
feels snappier; pressing the back button now takes you to the main menu instantly, when it used to
freeze for a while. Also, the device now plays a video while booting.
The menu now has a sound similar to coins in Mario bros.
Not a bounds and leps better than before, but at least its something.
Thanks again to GESATEC for posting.
